What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Valley Forge, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

Construction in Valley Forge, PA must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. When your blower door test in Valley Forge, PAmeets this requirement, you benefit from reduced energy bills and code compliance.

Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Use insulation that has the designated R-value and confirm it’s properly applied throughout the building envelope for maximum efficiency.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Valley Forge, PA

Before conducting blower door test in Valley Forge, PA, we make sure all heating, cooling, and ventilation fans are switched off. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Valley Forge, PA.
